Hello!
I have problem with mileage correction on this ezs. I read it with R270 and calculator didn't detect mileage(1J35D-0807(00)EEP orig.BIN),so i used NYO, it showed 814630, and i corrected it to 175124(1J35D-0807(00)EEP corrected.BIN). But when i connected it to the car, i jumped back to original mileage 202xxx. So i read ezs again(second.zip) NYO shows 175124...
What could it be?

I also corrected cluster to same mileage.

Maybe you don't read NYO4 instructions.
